100/1000Base Fiber Port Connection
The concept behind the duplex port and cable is quite straightforward. Suppose
you are connecting devices I and II. Contrary to electrical signals, optical
signals do not require a circuit in order to transmit data. Consequently, one of
the optical lines is used to transmit data from device I to device II, and the
other optical line is used to transmit data from device II to device I, for
full-duplex transmission.
All you need to remember is to connect the Tx (transmit) port of device I to the
Rx (receive) port of device II, and the Rx (receive) port of device I to the Tx
(transmit) port of device II. If you make your own cable, we suggest labeling
the two sides of the same line with the same letter (A-to-A and B-to-B or
A1-to-A2 and B1-to-B2).
